The product documentation is available from CA SUPPORT ONLINE (Internet searchable as well -- sample argument: docops tmc report site:ca.com). And has was mentioned, if your site has SAS and MXG (or CA MICS), then you have the opportunity to let those tools decode the fairly complex CA-1 TMC for you, while focusing on the analysis aspect.
